Diatoms Green Nanotechnology for Biosilica-Based Drug Delivery Systems

Pharmaceutics, 2018
Diatom microalgae are the most outstanding natural source of porous silica. The diatom cell is enclosed in a three-dimensional (3-D) ordered nanopatterned silica cell wall, called frustule.

Quantitative relationships between benthic diatom assemblages and water chemistry in Macquarie Island lakes and their potential for reconstructing past environmental changes [PDF]

, 2008
This study is the first published survey of diatom-environment relationships Oil sub-Antarctic Macquarie Island. Fifty-eight sites in 50 coastal and inland lakes were sampled for benthic diatoms and water chemistry. 208 diatom species from 34 genera were

Tailoring Se‐Mediated Co‐Co Dual‐Atom Sites for Oxygen and Iodide Electrocatalysis Toward High‐Efficiency and Ultradurable Zinc‐Air/Iodide Hybrid Batteries

Carbon Energy, EarlyView.
A Se‐mediated Co dual‐atom catalyst replaces sluggish oxygen evolution with efficient iodide oxidation in zinc‐air/iodide hybrid batteries. Se‐induced d‐p orbital hybridization optimizes adsorption, enabling a low 0.365 V voltage gap and superior durability, fundamentally overcoming conventional kinetic bottlenecks.

Ambident Reactivity in the Phenyl + NO Radical Recombination

Chemistry – A European Journal, EarlyView.
ABSTRACT The recombination reaction of nitric oxide (NO) with radicals via its oxygen atom, rather than the more common nitrogen site, offers an intriguing pathway to the formation of oxynitrenes. The photochemical isomerization of nitroso compounds into their corresponding oxynitrenes may involve such a step.

Possible role of microtubules in vesicular transport of matrix protein during sea urchin larval biomineralization

Developmental Dynamics, EarlyView.
Abstract Background Biomineralization is a vital biological process through which organisms produce mineralized structures such as shells, skeletons, and teeth. Microtubules are essential for biomineralization in various eukaryotic species; however, their specific roles in this process remain unclear.

Achievement of Transition Metal Chalcogenides/Oxides in Hydrogen Production by Seawater Electrolysis

EcoEnergy, EarlyView.
Transition metal chalcogenides (TMCs)/oxides have shown great application potential in seawater splitting for hydrogen generation due to their adjustable electronic properties, abundant active sites, and excellent catalytic performance. ABSTRACT Under the impetus of global “dual carbon” goals, green hydrogen has become a key component of the future ...

PondNet – towards a global network of experiments on the effects of climate change on aquatic ecosystems

Ecography, EarlyView.
Global change is reshaping the distribution of biodiversity and the functioning of ecosystems. Predicting the long‐term consequences of such changes remains a challenge due to a need for a clear understanding of the mechanisms underpinning ecosystem‐level responses, as well as the role of geographical and environmental contingencies.
